Non-comparative versus Comparative Advertising of Quality

Two firms produce a good with a horizontal and a vertical character- istic called quality. The difference in the unobservable quality levels determines how the firms share the market. We consider two scenar- ios: In the first one, firms disclose quality; in the second one, they send costly signals thereof. Under non-comparative advertising a firm advertises its own quality, under comparative advertising a firm adver- tises the quality differential. In either scenario, under comparative ad- vertising the firms never advertise together which they may do under non-comparative advertising. Moreover, under comparative advertis- ing firms do not advertise when the informational value to consumers is small.

An Architecture to offer Cloud-Based Radio Access Network as a Service

This paper addresses the novel notion of offering a radio access network as a service. Its components may be instantiated on general purpose platforms with pooled resources (both radio and hardware ones) dimensioned on-demand, elastically and following the pay-per-use principle. A novel architecture is proposed that supports this concept. The architecture's success is in its modularity, well-defined functional elements and clean separation between operational and control functions. By moving much processing traditionally located in hardware for computation in the cloud, it allows the optimisation of hardware utilization and reduction of deployment and operation costs. It enables operators to upgrade their network as well as quickly deploy and adapt resources to demand. Also, new players may easily enter the market, permitting a virtual network operator to provide connectivity to its users.

Theaterumbauten in der Schweiz (Radio-Interview von Dagmar Walser)

Reflexe, Radio SRF2Kultur Interview, Dagmar Walser, 31. Oktober 2014 Ausgangslage: Es häufen sich derzeit die Umbauten, die notwendigen Renovationen von Theaterhäusern, die in die Jahre gekommen sind. Das Theater Solothurn wird im Januar nach einem längeren Umbau fertig, in Bern endet die Spielzeit nächsten Frühling früher wegen der Renovationen, in Baden am Kurtheater wurde der längst notwendige Umbau wieder einmal verschoben Wie hängen Architektur und Ästhetik zusammen? Wie spielt man in einem historischen Ambiente zeitgenössische Stoffe? Weshalb werden Volksabstimmungen für den Erhalt der Theater jeweils hoch angenommen, und klagen die Theater doch über Publikumsschwund? Fragen, die ich dem Professor für Theaterwissenschaft Andreas Kotte in Bern stellen will.

Communion-over-Agency effects on advertising effectiveness

Gender-stereotypical portrayals of communal women and agentic men are highly common in advertising. But past research indicates that advertising effectiveness is higher when endorsers are portrayed as communal – irrespective of their gender. The aim of the current research is to explore this communion-over-agency effect on advertising effectiveness and its underlying mechanism. Two studies provide evidence for a communion-over-agency effect on advertising effectiveness (i.e., attitude toward the ad and brand). These studies show that the communion-over-agency effect on attitude toward the ad is mediated by endorser likeability (simple mediation). The effect on attitude toward the brand is mediated by endorser likeability and attitude toward the ad (serial multiple mediation). In concert, this research underscores the significance of communion (and agency) on endorser evaluation and advertising effectiveness.
